Enliven, elate (10)
I believe the answer is:
exhilarate
I believe this clue is a double definition.
'enliven' is the first definition.
(I've seen this in another clue)
'elate' is the second definition.
(I know that exhilarate is a more specific form of the action elate)
(Other definitions for exhilarate that I've seen before include "Thrill" , "Make very happy or very animated" , "Cheer" , "Enliven" .)
